您可以在FWP中使用“syndicated\\u post”挂钩，并在检查重复帖子的函数中使用挂钩。

add_action(\'syndicated_post\', \'fwp_check_duplicate\');

function fwp_check_duplicate ( $post ) {
    global $wpdb;
    $handle; 
    $possible_duplicate;

    $query = "SELECT id,guid 
               FROM $wpdb->posts 
               WHERE post_title = \'%s\' 
               AND post_date_gmt like %s";

    $sql = $wpdb->prepare(
                    $query, 
                    $post[\'post_title\'], 
                    gmdate(\'Y-m-d\', $post[\'epoch\'][\'issued\'])."%" );

    $results = $wpdb->get_results( $sql, ARRAY_N);
    foreach ( $results as $result ) { 
        if ( $result[\'guid\'] != $post[\'guid\'] ) { 
            $possible_duplicate = true; 
        } 
    }

    if ($possible_duplicate) {
     $post[\'post_status\'] = "draft";
    }
    // Otherwise continue to process.

    return $post;
}
